SNAKE: Montague brain-washed you, but JB had plans of his own.
JB: They must be stopped, Bruce. Montague, Nisha, Oscar, all MUST die!
JB: My name is "JB Chimpanski"... and I will have my revenge!
(Bruce's mind transitions)
BRUCE: My name is "JB Chimpanski"... and I will have my revenge!
OSCAR: You...again? I should've killed you in Vorkutlag.
(memory ends)
SNAKE: JB Chimpanski's been dead for 5 years! He died at Vorkutlag during the escape. All the years you thought he was with you - that was just in your mind!
(Snake pulls Bruce to his feet)
BRUCE: I trusted him...
SNAKE: That's why it worked! Montague programmed you to kill Potassius, but JB sabotaged you! He wanted revenge for all that Montague done to him. Montague, Nisha, Oscar, 3 new victims. There are gaps in your memory, periods where you went MIA and we couldn't account for you, but now that the brain-washing's been broken, all that lost time can come back.
